Abstract

1430581 Fluorinated hydrocarbons R N HASZELDINE and R ROWLAND 5 April 1973 [14 Jan 1972] 1988/72 Heading C2C [Also in Division C3] One or more hexafluoropropene units are inserted into the structure of an organic hydrocarbon material containing at least one aliphatic carbon-hydrogen bond and which is free of acetylenic and terminal ethylenic unsaturation, insertion being into said carbon-hydrogen bonds, not more than one unit being inserted into any one such bond, by contacting the hydrocarbon material with hexafluoropropene at 160- 350‹ C., pressure 1-250 atm. absolute, in the absence of free oxygen containing gas and of a free-radical forming chemical catalyst. The product of insertion into bond R-H is or The hydrocarbon material may for example be an alkane (methane, n-propane, isobutane and n-butane are exemplified) a cycloalkane (cyclopropane, cyclopentane and cyclohexane) a cycloalkene (cyclehexene) or an alkyl aromatic (m-xylene); in the examples one unit is inserted per molecule, and, with n-butane a product of insertion of two units is also obtained. Polymeric hydrocarbons may also be used (see Division C3). Products are useful chemical intermediates; their dehydrofluorination yields fluorinated olefins or dienes that may be polymerized or copolymerized; e.g. the hexafluoroheptane obtained from butane may be dehydrofluorinated to yield pentafluoroheptene or tetrafluoroheptadiene. Liquid fluorinated products are useful dielectric liquids, non-corrosive heat-exchange materials, solvents and lubricants.
